Is there a way to put the image viewer below the tree folder?

Hi, after a little while trying to do it I can not find the way to put the image viewer in the same column (above or below) as the tree folder, that would save me a ton of space honestly, it would be perfect but maybe I have to write a script or smt like that?

Not currently; it can only go on the right or bottom across the whole window (or sharing the right with the metadata panel if it's on as well).

Ok, thanks!
